A spectacular E30 M3 turbo S14 build by member DCR

If you are a BMW enthusiast, even in the slightest, you will appreciate a quality build like this. DCR's E30 M3 is simply one of the cleanest and best built custom turbo examples we have ever seen. The compression of the 2.5 liter motor was dropped to 8.1:1 and at just 9 psi it put down 265 whp. Impressive? Oh yes, and just take a look at that engine bay.

Will it not boost higher due to the tune or turbo? 8000 rpm? Nice, very nice.

No the banjo bolt blew off the back of the wastegate so this prevented the Autronic controlling the boost level. It had a 9psi spring in the wastegate so thats what it opened at. It was too hot to re-attach the bolt there and then.

That turbo is holding torque perfectly! Has a lot left. Perfect build, I'm jealous! Can't wait for the 14psi, 8000RPM dyno! I wouldn't be surprised if you make 400whp, which would be insanely fun in that car!
